I think the system we have is just fine. Everyone has the freedom to vote for whatever they want. If the same artists occupy the Hot 20 with the same kinds of pics all of the time, maybe because their friends vote for them, that only means more people need to get voting. 20, 30, even 70 votes, what's that really, when we have 40,000 or however many members? Not even a drop in the bucket. The only problem with the Hot 20 is that, outside of a very small but VERY vocal minority, no one cares about it in the slightest. If they did, they'd vote.
